Certified Treecare Safety Professional (CTSP) Practice Exam

When working in an insulated aerial lift, what is the minimum approach distance from energized electrical conductors?

1. 5 feet (1.52 meters)

2. 10 feet (3.05 meters)

3. 15 feet (4.57 meters)

4. 20 feet (6.1 meters)

The correct answer is: 10 feet (3.05 meters)

The correct minimum approach distance from energized electrical conductors when working in an insulated aerial lift is indeed 10 feet (3.05 meters). This distance is established to ensure the safety of workers operating in close proximity to live electrical equipment. It serves as a buffer zone designed to protect personnel from the risk of electric shock, as electricity can arc over distances that exceed the physical reach of conductors, particularly in wet weather or in cases where equipment might inadvertently come into contact with overhead lines. The 10-foot guideline is consistent with safety regulations and practices that underscore the importance of maintaining a safe distance to avoid electrical hazards. These standards take into account the unique circumstances faced when working at height and with large equipment like aerial lifts. Maintaining this distance helps ensure that operators can carry out their tasks without the added risk posed by nearby electric lines, enhancing overall workplace safety.
